I'll see if i can catch jmkasunich here in the morning. Bout nine his time.
no jmk yet
I may be lucky and leave tomorrow - w00t!
That would get you here in good time.
I'll be a bit late tomorrow, but more or less on time in Galesburg (tired though)
unless the machine acts up tomorrow
this (stupid fscking LabView) project I'm working on goes into a 625KW power supply tomorrow, for a customer demo on Tuesday
well - I'll be in IL, so that's OK. :)
it's really too bad. this is very cool hardware, but the only way to get it to do anything is by using LabView to develop the software and FPGA code
write an angry letter and bury it somewhere
look at http://www.ni.com/
and select CompactRIO from the hardware menu
I've let them know that I don't plan to become a 20-year veteran user of LabView
the reconfigurable embedded system is basically a tiny PC, with a CPU that I think has a 1GHz clock, 64M RAM, 512M flash, and either a 1- or 3-million gate FPGA
Hope it works and you can get away early.
we had to give up on the 10KHz loop rate for now - going down to 100Hz helps a lot ;)
and it's not overkill?
* fenn boggles
I'm amazed. just filtering ~12 analog inputs and a few housekeeping tasks takes around `M gates
1M, that is
and that's without any of the PID in the FPGA
the countdown begins.
Until I show off my misunderstandings of emc2.
Hi Alex. Working of taking a weekend day off?
working or. Darn can't type and I'm just getting started.
still compiling kernels for the livecd :)
this is just getting madder and madder
I tried that with knoppix. What a mess i made of it.
BTW -- There might be a bit of reward for you doing this.
nothing certain yet...
IF I ever finish it :))
what could be better reward than the admiration of his peers?
oh wait, I know one thing :-)
* alex_joni is afraid to know
at my age several things come to mind.
what is it?
the admiration of his peers, plus a cookie
I upgraded my laptop last night using synaptic.
This morning the ubuntu updated said I needed to upgrade.
No the other stuff.
what does it want you to upgrade now?
about 140 packages.
there have been quite a few security fixes, including all of X
Looked to me like it wanted to do the same thing twice.
I've been ignoring those on my laptop because I don't care, but I allowed it to update X on my desktop and it was ok
I wonder why this box doesn't want upgrading.
hasn't in a month.
probably you don't have the update repositories enabled
there are breezy-updates and breezy-security
I've got everything checked except the breezy sources.
try an apt-get update then? or hit refresh on the update-manager
guess I should uncheck em and update then check them again.
Done that a dozen times since I got here.
It does find the new emc and axis stuff.
well that's good
Now it's saying that it can't get an exclusive lock.
did you forget a sudo?
or some other apt thing is running?
but synaptic seems to think it's okay.
I think synaptic holds the lock while it's open
I didn't see any but I'll look again.
rayh: on the mazak is the spindle encoder counted with hardware or the encoder hal driver?
It's counted from a parport.
Nasir on the mailing list is asking about an stg lathe - so far that's untested, I don't know if the stg encoder stuff is compatible
cradek: not really, it can't zero the enc-count
I mean.. not yet
the driver was useable to some point, the encoder stuff wasn't decided back then
so guess it'll be for 2.0.1 or later
there needs to be a flag controlled by motion that says 'zero when you get index'
I think there is
I think that's all it needs...?
inside the driver it needs to actually zero the counter chips
and export zero-imp pins
those aren't right now
doesn't the card know how to do that itself? I think it needs to be in hardware
or are you saying the card knows how to do it, but the driver doesn't have the ability to instruct it to do that?
ok I see
unfortunately Nasir is out of luck for right now then
the card knows more than one way (either reset, or remember the count when zero imp happened)
he can use parport for the spindle then
and stg for the rest
* alex_joni curses very badly at debian
cradek: I successfully built a kernel for the install, along with initrd & all, but after it boots, it needs the kernel deb aswell :/
so I guess I need to make a deb for rtai, along with a new deb for emc2
* alex_joni breaks down in tears
your kernel is not compatible with the existing rtai/emc2 debs?
if you used the same patch and .config it should be...?
not the same name
so it won't even try
maybe I should just rename them ??
oh, and to make it really nice.. I can't use 2.6.12-magma as a name for the linux-source package
it complains that it doesn't have numbers in it
2.6.12-10.magma is ok, but not 2.6.12-magma :(
I could go on for another hour
but I won't :)
a live cd would be nice, but I'm not sure how much trouble it's worth
what I like about it, is that it's 100% just like an installed desktop
same as the user will get later
cradek: did you get an email from Nasir on the mailing list? I didn't..
he also sent it to me privately - it may not have come through the list yet
although he sent it yesterday mid-day
18 hrs? ago
btw, did you notice htat the arhives are gone?
do you know if that's on purpose, or just a temporary outage?
oh, they seem to be back now
cradek: seems SF's CVS is finally online again
I hope they have it all sorted out
rayh: paul was looking for you in #emc
has jmkasunich said anything about being around.
not that I've seen jmk
doing saturday morning chores
but I have a quick question for you
we talked about paper copies of handbook and hal book
I still have time to get stuff printed at staples (I think)
I was thinking of the first two chapters of the hal book only, and just stapled
There is a staples in town here, but Roland's church will print for 0.01 if we provide the paper.
I brought a case of paper so we should be good to go.
then (maybe) a few copies of the whole thing with bindings,
I can print a master here and hand to him.
I was gonna do it today, here
one less thing to do while there
That's fine with me.
I mean, hi John
any guess as to how many?
First two chapters probably 20-30.
I'd bet you could sell 20 copies of the whole book as well.
the problem with the "whole book" is that it will go out of date
tho folks who stick with 2.0.0 won't mind
for them it will be accurate until 2.1.0 comes out
Sure. And there are soft copies available.
maybe I'll do 20-30 of the first two, and 10 or so of the whole thing
Okay sounds good.
I've got a question about table layout here.
btw, is "here" Roland's place?
Where your main table was last year is the japax wire welder.
ok, guess no table there
Behind that is the punch press.
its gonna be crowded isn't it
Well we have lots of room the other way.
other side of the really big mill you mean?
JonE's bridgeport is going to be in front of the roll up door.
he's bringing the whole mill?
No roland is supplying and jon is fitting.
Beyond the big mill is quite a bit of room the the divider wall.
Should we put a set of developer desks in a square there.
is your phone free? this is slow
Or would it be better for developers to be beyond the wall, kinda in a corner.
Sure call the cardinal line in about 5 minutes and I'lll go over and get it.
duh, I just called your home number
I'll call cardinal
Why do I get the microsoft website when I click on "follow these instructions" on the emc2 install page of the wiki?
where on the wiki?
I got there by following install emc2
and in the first paragraph there is a link in the first paragraph "Chris Radek"
ok, found out why
where it says simply follow "these instructions"
the link was http://http://
and only that seems to be bringing up www.microsoft.org ?? odd
brings up soms strange page, maybe firefox is googling for the word
[20:57:11] <alex_joni> http://www.google.ro/search?q=http
wonder how much they payd for that
well, it's definite. I won't be arriving at Fest until Monday evening
how goes the FPGA?
imagine if you will, a 3M gate FPGA, and all it's doing is allowing some software (running on an attached PC-like machine) to read A/D and digital inputs, and write some outputs, and it does minimal filtering on the analog inputs
this very simple program takes up over 1M of those gates
holy bloat Batman!
it should be roughly 12 sets of an adder, a shifter, and a subtracter, plus the interface stull - it just boggles the mind
yes - holy boat
that would sink
the PID loop that was supposed to run at 10KHz is only running at 100Hz
(hole-y boat ;-)
yes, this holy bloated boat would sink ;)
(sorry - only got 3 hours sleep the last few nuights)
see - I meant to say nights
jmkasunich, about how long is the drive from your place to Roland's?
Hey John. I got a 4 phase stepper drive here.
SWP: ~ 9 hours I think
7 if you drive like Ray
It took me 6.5 from ann arbor with construction and such.
I was considering trying to do the drive in one long day, but since Cleveland is roughly half way there for me, I don't think I'll do that
What do I have to change to get stepgen to do that for me?
stepping_type = 4 or so
to whatever one gives you the pattern you want
then instead of step and dir pins, you'll have phase-A, phase-B, etc pins
route them to the parport pins you want to use
This is detailed in the hal_int doc?
there are several different 4-phase patterns
I've got the guy ringing out the plug now.
I think there is a fullstep and halfstep pattern
Okay. This is a fantastic opportunity.
with size 17 steppers.
I can bring a couple of very small stepper motors, if you like
I have nema17
's from old 5.25" floppy drives
4-phase, unipolar, from DigiKey - they'd be around NEMA 0.3 ;)
This guy just walked in with the thing wired from some old "kit" that never ran.
That is small.
* rayh goes off to read hal_intro again.
hmmm. I wonder if it would make sense to use a small stepper motor as an encoder replacement
no output at zero speed
encoders don't have any output at 0 speed either
but no matter how slow you turn it, you won't lose position
ah - no latched outputs - right
not true with a stepper
turn it slow enough and the output voltage is lost in the mud
righto - OK.
see - I'm short of sleep ;)
ok, another attempt :)
please let it work now
ok -it can work now
any time ;)
I'm slowly running out of cdr's
I should look into making a bootable DVD - I have either 200 or 400 blanks here
ah - 200
I suppose I could bring those, I have a burner in the big machine
yeah.. bring them over here
ok. send a ticket ;)
is row-boat ok?
as long as it's first class
yeah, you get the rudder
oops. time to go - dinner with the wife tonight (woo)
see you later
who wants an iso to test ;)
I'm running axis-sim in the LiveCD right now, chipping away at 3D-Chips
good job ales
[22:36:46] <alex_joni> http://dsplabs.utt.ro/~juve/blog/index.cgi/01147559232
if anyone cares to repeat the experience :)
Ubuntu LiveCD at: http://dsplabs.utt.ro/~juve/emc/emc2-ubuntu-livecd.iso
congratulations on the live cd
I wish I had time to try it :-/
I bet you learned a lot in the process
more than I bargained for :))
yes it's always that way
I think it makes a nice CD to pass around.. but it should get tested..
